ELECTRIC IGNITER FOR GAS-ENGINES.

Specicaton of Letters Patent. s applicati@ med July 27, 190s.

Patented March 30, 1909. serial No. 445,628.

Tiall whom it may concern'.

4Be it known .that I, IRA B. REED, a citizen' tion'and operation of which are herein fully` set forth, reference being had to the accompanying drawings which form a part hereof and in which,

Figure 1 is a plan view, a portion being broken `away vto expose other portions to view.3 2 is a side elevation. v Fig. 3 is an y passesloosely.

Referringto the drawing the various details o'r elements of my device are as follows z-- 1 is a stationary, insulated electrode.

2 i's a reciprocating electrode.

3, 3, are solenoids.

4, 4, are plungeis.

5 isa yoke4 connecting the plungers and through which the reciprocating electrode 2 6 is a base or body, and is provided with a suitable screw threaded plug 6 by means of which the device is secured inthe cylinder of a .gasengine 7, 8, and9, ardbinding posts by means of which the necessary conductors or'wires are attached. s 1 10-is a spring which maintains the contact of the electrodes when n current is iowing through the igniter.

Vhen my device' is in operation it is secured in thecylinder cfa gas engine in the usual manner, the electrode being in the combustion chamber. One pole of a suitable electric generator is then attached to any portion of the gas engine, and the other pole of said generator is attached to the bindin screw 7.

When no current is flowing through' the igniter, the spring 10 serves to keep the elec trodes in contact. As soon as the current is permitted to flow, by the action of any suitable circuit closer, not shown-which, of course, in this case is an automatic device or timer actuated by the gas engine-the plungers are drawn into the solenoids, and as the yoke. engages the pin 1l, the reciprocating electrode is drawn backward, and breaks the cpntact between the two electrodes, which causes 'an arcing i of the current and a spark results. The solenoids and plungers here shown act according to the well known laws governing electro magnets and their armatures, and as long as the current .flows the plunger-s will vibrate rapidly and thus indicate the proper action of the device. When the current is broken by the timing device aforesaid, spring 10 carries the electrode 2 forward to contact with the electrode 1.

The contact faces of the electrodes 1 and 2 are'positioned at an an let'o the line of travel of the reciprocating e ectrode, so that said electrodes meet with somewhat of a wiping action, which tends to keep their contact faces clean and free from-carbon deposits, thereby maintaining their efficiency. Furthermore, said angu ar arrangement, by-reason of producing a more gradual separation of the electrodes, causes a more extended and intense arc, hence my ignlteris more certain and reliable in its action'th'an electrodes havin direct or square contact faces.

or the purpose of preventin any turning of the* movable electrode, 2 an for the purpose of at all times insuring its proper aline- -m-ent with the fixed electrode 1, the stem/of electrode 2 is made s uare at 12 and passes through a square ho e which is provided therefor in the frame 13, in which the solenoid 3 is mounted.

` What I claim is:

In an electric igniter for gas engines, a stationary electrode, a reciprocating electrode adapted to be moved into and out of contact with said stationary electrode, a spring adapted to maintain said reciprocating-electrode in said contact posit-ion, solenoids having plungers, a yoke connecting the plungers of said solenoids, said yoke being adapted to engage said-reciprocating electrodeand to be IRA B.
